I have not done well in jee main January attempt.then which marks should I fetch in April jee main to secure rank between 10000-15000 rank?will marks vs rank differ in this year as full marks is 300.

Dear Aspirant

Don't take stress and forget about January attempt and try to focus on April session .If you want rank between 10k to 15k then you should score around 180+ to secure good rank. This rank can be acheived if you are dedicated towards your goal.Just try to solve previous year question papers of jee main .Try to attempt maximum practice and mock test so you can acheive good score.

Thanks
All the very best
